Founder's Biography

MEET JOHN LEAH

Technical Director · Systems Architect · Master Craftsman · Music Industry Veteran · Environmental Innovator

John Leah is a technical leader whose career spans global touring productions, national energy-efficiency programmes, government-level environmental advocacy, award-winning craftsmanship — and thirty-five years inside the machinery of the music industry. That last thread is the one that explains the others: almost everything John has built, from carbon-mapping databases to virtual-reality world tours to band-management platforms, traces back to a single night in a Manchester rehearsal room.

THE NIGHT THAT STARTED IT

In 1992, aged twenty-two and armed with a borrowed video camera, John filmed a friend's band at their first gig at The Boardwalk in Manchester. He walked in knowing nothing about bands, sound, lighting or the strange economy backstage — and walked out as their manager, on the simple grounds that the alternative was nobody. That night he also made a friendship that would resurface, decades later, at the frontier of music technology.

Within a year John had taken over a struggling rehearsal complex on Dumers Lane in Radcliffe and renamed it Apocalypse Studios. Fifteen bands rehearsed there, most of them broke. John's answer was a co-operative: every member of every band bought one ticket to a show and sold two more, so a single night at The Boardwalk could fill three hundred places with the scene's own energy. Bands stopped working in silos, went to each other's gigs, and the studio thrived. It was John's first working growth system — designed for musicians with no money and no industry experience, run on trust and simple arithmetic.

The alumni of that room went on to remarkable things. A young band who rehearsed at Apocalypse renamed themselves Elbow and became one of Britain's most garlanded groups — Mercury Prize, Brit Award, number-one albums, an Olympic ceremony. Others from that scene now play in some of Manchester's best-known acts, from the pioneers of acid house to the touring bands of post-punk legends. John went on to manage bands through European tours, run a record label with the frontman of one of the city's most influential groups, and later work at the heart of a much-publicised anti-fracking political campaign — technical producer of its nightly celebrity bed-in broadcast, filmed in the spirit of Lennon and Ono, while a Channel 4 series documented the campaign around him.

Why John builds for musicians

WHY JOHN BUILDS FOR MUSICIANS

John still works where he started. He supports a nationally touring act playing rooms from Sheffield to the south coast, and is stepping in to manage a brand-new original band — both fronted by the friend he met the very first day he pointed a camera at a band, more than thirty years ago.

Every platform John builds for musicians — gig management, ticketing, touring finance, fan growth — encodes something he learned the hard way: the Apocalypse co-operative is a growth engine; the tour books of Björk Digital are logistics templates; three decades of watching brilliant, unsigned bands stall for want of a manager is the reason the software exists. His mission is specific: give fledgling bands, who have little or no experience of managing themselves, the systems a thirty-five-year insider would run for them — finding gigs, selling tickets, building an audience, and keeping the money straight — so that talent stops being lost to inexperience.
